Additionally or alternatively, STAs may communicate with each other via peer-to-peer transmissions 130, 132. Additional description related to certain communications is provided throughout the present disclosure.

FIG. 2 is a diagram 200 illustrating a non-limiting example of wireless communication between an AP and one or more STAs according to some aspects of the present disclosure. AP 110 may have one or more radios. AP 110 may have one or more antennas 212, 214. STA 120 may include a primary radio (PR) 222 and a secondary radio (SR) 224. STA 120 may include one or more antennas 226, 228. Without deviating from the scope of the present disclosure, STA 120 may have one or more PRs 222 and/or one or more SRs 224. Without deviating from the scope of the present disclosure, SR 224 may alternatively or interchangeably be referred to by various other terms, such as an awaken radio/receiver, a low-power radio/receiver, and/or various other suitable terms. In some aspects, SR 224 may be configured to sometimes consume less power than PR 222. In some aspects, SR 224 may consume and/or utilize less power, resources, etc. than consumed and/or utilized by PR 222.

In some aspects, an apparatus may include one or more receivers and/or antennas. In some aspects, the apparatus may have one or more primary/main receivers and/or one or more secondary receivers. A secondary receiver may also be referred to by various terms, such as an awaken radio/receiver, a low-power radio/receiver, and/or other terms. The secondary receiver(s)/radio(s) may consume and/or utilize less power, resources, etc. than the primary receiver(s)/radio(s). The secondary receiver(s) may be configured to awaken one or more primary/main receivers under certain circumstances, such as after/upon receiving a certain type of packet (e.g., an awaken packet). In some aspects, an apparatus may include one or more receivers and/or antennas.

One of ordinary skill in the art will understand that certain terms described/mentioned herein may be interchangeable without necessarily deviating from their respective meaning. The terms packet, frame, beacon, signal, transmission, communication, and/or various other suitable terms may be interchangeable without necessarily deviating from the scope of the present disclosure and/or without necessarily deviating from their respective meaning. The terms awaken packet, request packet, awaken request packet, and/or various other suitable terms may be interchangeable without necessarily deviating from the scope of the present disclosure and/or without necessarily deviating from their respective meaning. The terms request packet, awaken response packet, and/or various other suitable terms may be interchangeable without necessarily deviating from the scope of the present disclosure and/or without necessarily deviating from their respective meaning.

In some aspects, the apparatus may utilize one or more of the secondary receivers (e.g., awaken radio(s)/receiver(s)) to receive a packet while its primary/main receiver(s)/radio(s) is turned/powered off or in a low-power mode/state. In some aspects, the received packet may be (1) configured to trigger, awaken, turn on, and/or cause a high(er) power mode to occur for one or more of the receivers/radios (e.g., one or more primary/main radios/receivers) of the apparatus, and/or (2) configured to trigger a response packet. After, in response to, and/or in association with receiving such a packet, the apparatus may (1) awaken the one or more primary/main radios/receivers, and/or (2) cause a response packet to be communicated. If the main/primary radio(s)/receiver(s) is turned/powered off or in the low-power state/mode, the apparatus may refrain or be unable to transmit a corresponding transmission (e.g., response). In some aspects, the apparatus may transmit a power save poll frame. In some aspects, after transmitting such a frame, the apparatus may receive a data packet and subsequently transmit an acknowledgement frame/packet.

In some aspects, the receiver/STA may receive a packet. The packet may or may not include a preamble. The packet may be an awaken packet, a data packet, an uplink transmission request, a trigger packet, a beacon, and/or various other types of packets. In some aspects, the packet may be and/or may be encoded as an orthogonal frequency division multiplexing (OFDM) packet. In some aspects, the packet may be modulated using various keying/modulation techniques, such as frequency shift keying, amplitude shift keying, phase shift keying, on off keying, quadrature amplitude modulation, and/or various other types of modulation or keying/modulation techniques.

In some aspects, the awaken request packet may include various fields, parameters, indications, data, and/or other information without deviating from the scope of the present disclosure. In some aspects, the awaken request packet may include a field/parameter/indication/data/information indicating/corresponding to/associated with an indication, purpose, intention, objective, and/or other state/mode/configuration associated with the STA(s) that receives that awaken request packet. In some aspects, such indication, purpose, intention, objective, or other state/mode/configuration of the STA(s) may include a transmission, e.g., an UL transmission, of information/data, which may be corresponding to or be after, in response to, and/or in association with receipt of the awaken request packet. In such aspects, the STA(s) may communicate/transmit UL data/information without/before polling, or transmitting a poll message (e.g., a power save poll) to, the apparatus that communicated the awaken request packet, and/or without/before receiving a poll message (e.g., an uplink data poll) from the apparatus that communicated the awaken request packet.

In some aspects, such an indication, purpose, intention, objective, and/or other state/mode/configuration of the STA(s) may include a setting, configuration, or initialization of certain parameters of the STA(s) that may have received the awaken request packet. In such aspects, the STA(s) may communicate/transmit information indicating or corresponding to one or more preferences of the STA(s) (e.g., one or more preferences associated with settings/parameters/configurations of UL communication) without polling, or transmitting a poll message (e.g., a power save poll) to the apparatus that communicated the awaken request packet, and/or without/before receiving, from the apparatus that communicated the awaken request packet, information indicating or corresponding to one or more preferences of the STA(s) (e.g., one or more preferences associated with settings/parameters/configurations of UL communication).

A radio may communicate (e.g., transmit and/or receive data/information) using a wireless communication medium with another apparatus. The term ‘radio’ may refer to any set of one or more components that can be utilized to generate radio waves. Such components may include any one or more structures, modules, circuits, processors, algorithms, computer-readable medium, memory, interfaces, transceivers, antennas, and/or various other aspects, regardless of whether described herein, that can implement the various features, functions, operations, elements, methods, and/or aspects described herein. Non-limiting examples of such one or more components are described herein with reference to FIGS. 5 and 6 for AP 110 and STA 120, respectively. The various features, functions, operations, elements, methods, and/or aspects described herein may be implemented in varying designs for different radios without necessarily deviating from the scope of the present disclosure. The term ‘radio’ may alternatively or interchangeably be referred to as a receiver, a transmitter, a transceiver, a transceiver circuit, a radio circuit, and/or various other suitable terms. Although various examples provided herein describe STA 120 as including two radios (e.g., PR 222, SR 224), STA 120 may include any number of radios (e.g., more than two radios) without necessarily deviating from the scope of the present disclosure.

As illustrated in FIG. 1 , STA 120 may communicate wirelessly with AP 110, and AP 110 may communicate wirelessly with STA 120 and, possibly, other STA(s) 240, which may have its/their own PR (e.g., PR 232, including or using antenna 236) and/or SR (SR 234, including or using antenna 238). Such communication(s) may include concurrent and/or independent streams (e.g., of data/information) to and from one or more apparatuses. Additional description related to various structures, modules, circuits, processors, algorithms, computer-readable medium, memory, interfaces, transceivers, antennas, and various other aspects of AP 110 and STA 120 is provided throughout the present disclosure, including description provided herein with respect to FIG. 5 and FIG. 6 , respectively.

FIG. 3 is a diagram 300 illustrating a non-limiting example of various communications at various times according to some aspects of the present disclosure. FIG. 3 is a diagram 300 illustrating non-limiting examples of various communications between AP 110 and STA 120 according to various aspects of the present disclosure. In some aspects, at one or more times (e.g., including T₁ and/or T₂), AP 110 may communicate with STA 120. In some aspects, such communications may pertain to capabilities, parameters, settings, configurations, and other aspects that may affect one or more states, modes, configurations, parameters and/or future communications between AP 110 and STA 120.

In some aspects, AP 110 and STA 120 may negotiate various parameters, settings, and/or configurations, which may relate to operation(s) of AP 110, STA 120, PR 222 and/or SR 224. In some aspects, at time T₁, STA 120 may transmit and AP 110 may receive an UL communication 310. In some aspects, the UL communication 310 may be or include a request, a request packet, a timing management signal, a timing signal, and other suitable terms without deviating from the scope of the present disclosure. Various aspects related to such UL communication 310 are provided in greater detail throughout the present disclosure. In some aspects, at time T₂, AP 110 may transmit and STA 120 may receive a DL communication 312. In some aspects, the DL communication 312 may be or include a response, a response packet, a timing management signal, timing signal, and other suitable terms without deviating from the scope of the present disclosure. Various aspects related to such DL communication 312 are provided in greater detail throughout the present disclosure.

Although UL communication 310 is illustrated as a single communication, and DL communication 312 is illustrated as a single communication, multiple UL communications and/or multiple DL communications can be implemented without deviating from the scope of the present disclosure. Any or all aspects described herein with reference to an ‘UL communication 310’ and/or ‘DL communication 312’ can be respectively included in a singular DL communication 310 and/or singular UL communication 312 (as shown in FIG. 3 ) or alternatively included in discrete/separate UL communications and/or discrete/separate DL communications taking place at varying times (even though not shown in FIG. 3 ) without deviating from the scope of the present disclosure. In other words, any description provided herein with reference to an ‘UL communication 310’ may be included in a singular UL transmission or included in different UL communications occurring at different times, and/or any description provided herein with reference to ‘DL communication 312’ may be included in a singular DL transmission or included in different DL communications occurring at different times.

In some aspects, STA 120 may utilize PR 222 for UL communication 310 and/or DL communication 312, but STA 120 may alternatively utilize its SR 224 for UL communication 310 and/or DL communication 312 without deviating from the scope of the present disclosure. Although the illustration provided in FIG. 3 depicts that, in some aspects, such UL communication 310 may occur prior to such DL communication 312, this may not necessarily be a limitation of the present disclosure. For example, in some aspects, such DL communication 312 may occur prior to such UL communication 310 without deviating from the scope of the present disclosure. Although the illustration in FIG. 3 depicts that, in some aspects, both UL communication 310 and such DL communication 312 can occur, this may not necessarily be a limitation of the present disclosure. For example, in some aspects, such UL communication 310 may occur without such DL communication 312 ever occurring, and, in some other aspects, such DL communication 312 may occur without such UL communication 310 ever occurring.

In some aspects, certain communications (e.g., DL communication 310 and/or UL communication 312) may occur while PR 222 222 is in a high power state/mode 314. In some aspects, certain communications (e.g., DL communication 310 and/or UL communication 312) may occur while the SR 224 is in a low power state/mode 316. Generally, the term ‘high power state/mode’ may alternatively or interchangeably be referred to as an active state/mode, awake state/mode, an on state/mode, a powered up/on state/mode, a turned up/on state/mode, and/or various other suitable terms without deviating from the scope of the present disclosure. In some aspects, the term ‘high power state/mode’ may refer to a state/mode in which the power utilized (e.g., by PR 222 and/or SR 224) is above or greater than a certain threshold value (e.g., threshold power value). Generally, the term ‘low power state/mode’ may alternatively or interchangeably be referred to as a doze state/mode, a power-save state/mode, an off state/mode, a powered down/off state/mode, a turned down/off state/mode, and/or various other suitable terms without deviating from the scope of the present disclosure. In some aspects, the term ‘low power state/mode’ may be referred to as a state/mode in which no/zero power is utilized (e.g., by PR 222 and/or SR 224). In some aspects, the term ‘low power state/mode’ may refer to a state/mode in which the power utilized (e.g., by PR 222 and/or SR 224) is below or less than a certain threshold value (e.g., threshold power value).

In some aspects, the PR 222 may sometimes alternate between a high power state/mode 314, 334 and a low power state/mode 322. Such alternating may occur when STA 120 or its PR 222 is in a power-save state/mode or a duty cycle state/mode. Although such alternating is illustrated in FIG. 3 , in some aspects, the PR 222 may not perform such alternating and may be in a, e.g., continuous high power state/mode (e.g., without the low power state/mode 322). In some aspects, the SR 224 may sometimes alternate between a high power state/mode 324, 328 and a low power state/mode 316, 326, 336. Such alternating may occur when STA 120 or its SR 224 is in a power-save state/mode or a duty cycle state/mode. Although such alternating is illustrated in FIG. 3 , in some aspects, the SR 224 may not perform such alternating and may be in a, e.g., continuous high power state/mode (e.g., without the low power state/mode 326). Various aspects pertaining to certain states, modes, configurations, and parameters associated with operation(s) of STA 120, the PR 222, and/or the SR 224 is provided throughout the present disclosure.

In some aspects, STA 120 may await receipt, e.g., at/including times T₃, T₄ and T₅, which may be while the PR 222 is in the low power state/mode 322. In some aspects, at time T₆, AP 110 may transmit and STA 120 may receive a packet 320. In some aspects, the SR 224 receives the packet 320 while the SR 224 is in a high power state/mode 328. In some aspects, the PR 222 may be in a while low power state/mode 322 when AP 110 transmits and STA 120 (e.g., utilizing SR 224) may receive the packet 320. In some aspects, the packet 320 may alternatively or interchangeably be referred to as an awaken packet, an awake packet, an awaken request packet, and/or various other suitable terms without deviating from the scope of the present disclosure. Various aspects related to the packet 320 and operations by STA 120 in relation to the packet 320 are provided throughout the present disclosure.

In some aspects, following communication of the packet 320, STA 120 may initiate, e.g., at time T₇, a transition of the PR 222 from a low power state/mode 322 to a high power state/mode 334. For example, after a transition period 338, the PR 222 may be in a high power state/mode 334 by time T₈. In some aspects, the SR 224 may be in a low power state/mode 336 after the PR 222 transitions to a high power state/mode 334.

In some aspects, at time T₉, STA 120 (e.g., utilizing PR 222) may transmit and AP 110 may receive a message 330. In some aspects, at time T₁₀, AP 110 may transmit and STA 120 (e.g., utilizing PR 222) may receive a response packet 332. Various aspects pertaining to such packets 330, 332 are provided throughout the present disclosure. In some aspects, at time T₁₁, AP 110 and STA 120 (e.g., utilizing PR 222) may perform UL and/or DL communication of various information 340, possibly including data packets with payloads. In some aspects, at time T₁₂, AP 110 and STA 120 (e.g., utilizing PR 222) may communicate information configured to suspend or disregard certain negotiated parameters, settings, and/or configurations, which may relate to operation(s) of AP 110, STA 120, PR 222 and/or SR 224.

Although FIG. 3 depicts various aspects, including various communications (e.g., 310, 312, 320, 330, 332, 340, 350) possibly occurring at various times (e.g., T₁, T₂, . . . T₁₂) while one or more radios (e.g., 222, 224) of STA 120 may be in various states/modes, modes, or configurations (e.g., 314, 322, 334, 316, 324, 326, 328, 336), such various aspects are provided to facilitate description of just a few of the many combinations, mixtures, and permutations of such various aspects that can exist without deviating from the scope of the present disclosure. In some aspects, fewer than all of such various aspects can exist without deviating from the scope of the present disclosure, and any combination, mixture, or permutation of any one or more of such various aspects is within the scope of the present disclosure. For example, although FIG. 3 depicts that various communications (e.g., 310, 312, 320, 330, 332, 340, 350) may occur, it is possible for one or more of such communications to not occur without deviating from the scope of the present disclosure, and it is alternatively or additionally possible for one or more additional communication (not described herein) to occur without deviation from the scope of the present disclosure. Any indications of time are merely provided for illustrative purposes, and such indications are not necessarily to scale, not necessarily intended to limit the sequence or order of such communications, nor necessarily provided to suggest that certain communications have to occur at certain specific times.

FIG. 4 is a diagram 400 illustrating a non-limiting example of various operations according to some aspects of the present disclosure. In some aspects, at block 402, an apparatus (e.g., AP 110 and/or STA 120) may negotiate various parameters, settings, and/or configurations, which may relate to operation(s) of AP 110, STA 120, PR 222, and/or SR 224.

In some aspects, the UL communication 310 may be or include a request packet. In some aspects, the DL communication 312 may be or include a response packet. In some aspects, STA 120 may use PR 222 to transmit, and AP 110 may receive, a request packet. After or in response to transmitting the request packet, AP 110 may transmit and STA 120 may use PR 222 to receive a response packet. In some aspects, the request packet and/or the response packet include information corresponding to or configured for negotiating one or more parameters associated with one or more power modes, states, or configurations of SR 224. In some aspects, the request packet and/or the response packet include information corresponding to a duty cycle of SR 224. In some aspects, the duty cycle of SR 224 includes turning/powering on/off the SR 224 or SR 224 entering into a low/lower state mode and/or a high/higher power state/mode. In some aspects, the request packet and/or the response packet includes information corresponding to timing for turning on SR 224 or SR 224 entering/being in a high power state/mode.

In some aspects, the apparatus may transmit a packet, such as a request packet (e.g., an awaken request packet). After, in response to, and/or in association with transmitting such a packet, the apparatus may receive a response packet (e.g., an awaken response packet). In some aspects, the communication (e.g., reception and/or transmission) of such a request packet and/or such a response packet may be performed using the main/primary receiver(s)/radio(s) (described above). In some aspects, the communication (e.g., reception and/or transmission) of such a request packet and/or such a response packet may be performed using the secondary radio(s)/receiver(s) (described above).

In some aspects, such a request packet and/or response packet may include information (e.g., one or more fields) corresponding to awakening one or more primary/main receivers of the apparatus under certain circumstances, such as after/upon receiving a certain type of packet (e.g., an awaken packet).

In some aspects, such a packet (e.g., awaken packet) may be (1) configured to trigger, awaken, turn on, and/or cause a high(er) power mode to occur for one or more of the receivers/radios (e.g., one or more primary/main radios/receivers) of the apparatus, and/or (2) configured to trigger a response packet. As described above, after, in response to, and/or in association with receiving such a packet, the apparatus may (1) awaken the one or more primary/main radios/receivers, and/or (2) cause a response packet to be communicated.

In some aspects, an apparatus may receive and/or transmit a frame configured to communicate mode signaling or a request by the apparatus to enter/exit/switch-to (or to be signaled to enter) a particular mode (e.g., an awaken mode, as described herein). In some aspects, the apparatus may enter/exit/switch-to a particular mode (e.g., an awaken mode, as described herein) without explicit signaling (e.g., without receiving and/or transmitting a particular frame configured to communicate mode signaling or a request by the apparatus to enter/exit/switch-to (or to be signaled to enter) a particular mode. In some aspects, an apparatus (e.g., STA) may receive a packet (e.g., an awaken request packet, as described herein) (e.g., using its secondary/awaken radio/receiver), while in an awaken mode (as described herein). After, in response to, and/or in association with receiving the awaken request packet, the apparatus (e.g., STA) may enter into an active/normal mode (or power up/on or put in a non-low (e.g., normal/high) power state its main/primary radio/receiver) and initiate communication (e.g., DL or UL) with another apparatus (e.g., AP). In some aspects, the apparatus (e.g., STA) may receive data (e.g., a data packet/frame, perhaps with a data subfield in the data packet/frame set/equal to zero), e.g., using it primary/main radio/receiver. After, or in response to, and/or in association with receiving that data/data-packet/data-frame, without explicit signaling to/from the other apparatus (e.g., AP) (e.g., without receiving a signal/frame/packet indicating or requesting a transition/switch/change of a mode of operation (e.g., a transition/switch to or from an awaken mode) of the apparatus (e.g., STA)), the apparatus (e.g., STA) may switch-to/transition (back)/(re)enter an awaken mode (as described herein), e.g., if/only-if/provided-that an operating parameter of the secondary/awaken radio/receiver has not been changed/altered to require otherwise.

In some aspects, an apparatus (e.g., STA) may be ready (e.g., have in its queue) for UL transmission/communication of a packet/frame while in an awaken mode (as described in herein). In such aspects, without explicit signaling to/from the other apparatus (e.g., AP) (e.g., without receiving a signal/frame/packet indicating or requesting a transition/switch/change of a mode (of operation) (e.g., a transition/switch to or from an awaken mode) of the apparatus (e.g., STA)), the apparatus (e.g., STA) may transmit the data (e.g., data packet/frame) buffered/ready for UL transmission/communication (e.g., to the other apparatus (e.g., AP)) (e.g., following a contention period).

In some aspects, STA 120 may transmit and AP 110 may receive a timing management signal configured to set or affect timing information, including a duration of time to operate SR 224 in a high power state/mode or to maintain or power on/up SR 224 (e.g., in a high power state/mode), corresponding to communication of the packet 320 (e.g., awaken packet) and/or its response 330 (e.g., response to awaken packet). In some aspects, STA 120 may transmit and AP 110 may receive a timing management signal configured to set or affect a timing aspect, including a duration of time to operate SR 224 in a high power state/mode or to maintain or power on/up SR 224 (e.g., in a high power state/mode). In some aspects, STA 120 may transmit and AP 110 may receive a timing management signal configured to set or affect timing aspects, including a start time, a duration, and/or an end time, of operating SR 224 in a high power state/mode or powering/turning on/up SR 224 (e.g., in a high power state/mode).

In some aspects, the DL communication 312 may be or include a timing management signal. In some aspects, AP 110 may transmit and STA 120 may (e.g., using PR 222) receive a timing management signal configured to set or affect a beginning time corresponding to receiving of the packet 320 (e.g., awaken request packet). In some aspects, AP 110 may transmit and STA 120 may (e.g., using PR 222) receive a timing management signal and, based on the received timing management signal, set or affect timing aspects, including a beginning time, a duration, and/or an end time, of operating SR 224 in a high power state/mode or of powering/turning up/on SR 224 (e.g., in a high power state/mode). In some aspects, AP 110 may transmit and STA 120 may (e.g., using PR 222) receive a timing management signal configured to set or affect timing information, including a duration of time to operate SR 224 in a high power state/mode or to maintain or power on/up SR 224 (e.g., in a high power state/mode), corresponding to communication of the packet 320 (e.g., awaken packet) and/or its response 330 (e.g., response to awaken packet). In some aspects, the timing management signal (e.g., of the UL communication 310 and/or DL communication 312) includes a sequence modulated by on off keying.

In some aspects, the apparatus may receive a timing management signal. The timing management signal may include, be utilized for, and/or be configured to set, modify, adjust, confirm, and/or otherwise affect timing information (e.g., a start/starting time, a beginning time, an end/ending time, a duration, a time period, a timing offset, timing information or a start time of a subsequent timing management signal, a duration of time to maintain or power/turn on/up a primary/main and/or secondary radio(s)/receiver(s), etc.) corresponding to communication (e.g., reception/transmission) of the (e.g., current or one or more subsequent) awaken packet(s) and/or response packet(s) by the apparatus. In some aspects, the apparatus may set, modify, adjust, confirm, and/or otherwise affect a timing aspect e.g., a start/starting time, a beginning time, an end/ending time, a duration, a time period, a timing offset, timing information or a start time of a subsequent timing management signal, a duration of time to maintain or power/turn on/up a primary/main and/or secondary radio(s)/receiver(s), etc.) of powering/turning/keeping-powered on/up of the primary/main radio(s)/receiver(s) and/or secondary radio(s)/receiver(s) based on the timing management signal.

In some aspects, the timing management signal may comprise a sequence modulated by any of the keying/modulation techniques, such as frequency shift keying, amplitude shift keying, phase shift keying, on off keying, quadrature amplitude modulation, and/or various other types of modulation or keying/modulation techniques. In some aspects, the timing management signal may be detected by the secondary radio(s)/receiver(s) without utilizing the primary/main radio(s)/receiver(s) (e.g., while the primary/main radio(s)/receiver(s) is powered/turned off/down). In some aspects, the timing management signal may be communicated (e.g., received) periodically.

In some aspects, the apparatus may detect/determine that the timing management signal was not received (e.g., during an expected time/time-period, based on its periodicity). In response, the apparatus may modify, update, revise, and/or alter a timing aspect (e.g., a start/starting time, a beginning time, an end/ending time, a duration, a time period, a timing offset, etc.) of its primary/main receiver(s)/radio(s) and/or secondary receiver(s)/radio(s). In some aspects, this may be performed in a manner that increases a likelihood that a subsequent timing management signal will be received/detected by the apparatus and/or its primary/secondary radio(s)/receiver(s). In some aspect, the likelihood may be increased by increasing the power on/up duration/period of the primary/main radio(s)/receiver(s) and/or secondary radio(s)/receiver(s) (relative to a preceding power on/up duration/period of the primary/main radio(s)/receiver(s) and/or secondary radio(s)/receiver(s)).

In some aspects, the DL communication 312 includes a packet (e.g., request packet) that includes a parameter corresponding to a mode/state associated with STA 120. In some aspects, AP 120 transmits and STA 120 receives (e.g., using PR 222) the packet (e.g., request packet) that includes the parameter corresponding to a mode associated with STA 120, and STA 120 waits, based on the received parameter, to operate PR 222 in a high power state/mode or to turn on/up PR 222 until a time that corresponds to that mode/state.

As described herein, a packet (e.g., awaken request packet) may sometimes be referred to as a frame (e.g., awaken frame), beacon (e.g., awaken beacon), signal (e.g., awaken signal), transmission (e.g., awaken transmission), communication (e.g., awaken communication), and/or various other suitable terms without necessarily deviating from the scope of the present disclosure. In some aspects, a packet (e.g., awaken request packet) and/or a beacon (e.g., awaken beacon) may include a field/parameter/indication/data/information indicating/corresponding to/associated with an indication, purpose, intention, objective, and/or other state/mode/configuration associated with the STA(s) that receives that packet and/or beacon. After, in response to, and/or in association with receiving such and/or based on such field/parameter/indication/data/information, an apparatus (e.g., STA(s) may wait to turn-on/activate/enable/duty-cycle-on/power-up/power-on its primary/main radio/receiver and/or secondary radio/receiver until a time/duration/period that corresponds to the indication, purpose, intention, objective, or other state/mode/configuration. For example, if such indication, purpose, intention, objective, and/or other state/mode/configuration indicates a time/duration/period that a subsequent/next/later DL communication of interest will be transmitted from one apparatus (e.g., AP) to another apparatus (e.g., that/those STA(s)), then the apparatus (e.g., STA(s)) may determine to not turn-on/activate/enable/duty-cycle-on/power-up/power-on its primary/main and/or its secondary radio/receiver until a time/period/duration that corresponds to that DL communication of interest, which can conserve power that might otherwise be expended during a corresponding duration/period of time.

Such subsequent/next/later DL communication may or may not be the DL communication that immediately follows DL communication of the aforementioned packet (e.g., awaken request packet) and/or beacon (e.g., awaken beacon). For instance, one or more DL communications (e.g., not of interest to that/those STA(s)) may occur in between that packet/beacon and the DL communication of interest. Non-limiting examples of such DL communication(s) of interest may include but may not be limited to another packet, another beacon, another signal, another transmission, which may or may not include information/parameter/field/indication corresponding to traffic information (e.g., traffic information message), delivery information (e.g., delivery traffic information message), a group identifier/address information (e.g., associated identifier message), receiver/reception information (e.g., receiver/reception indication), on-duration information (e.g., a duration/period of time to maintain one or more of its radio(s)/receiver(s) in an on/powered-on/powered-up), and/or various other suitable types of information.

In some aspects, the DL communication 312 may be or include a packet (e.g., request packet) that includes an indication that indicates a process to perform in relation to awakening PR 222. In some aspects, awakening PR 222 may refer to transitioning PR 222 from being in a low/lower power state/mode to a high/higher power state/mode. In some aspects, awakening PR 222 may refer to switching from operating PR 222 in a low/lower power state/mode to operating PR 222 in a high/higher power state/mode. As described in greater detail herein, in some aspects, a low/lower power state/mode may refer to operating a radio (e.g., PR 222 and/or SR 224) according to a power state/mode that is less than a threshold power value, and/or a high/higher power state/mode may refer to operating a radio (e.g., PR 222 and/or SR 224) according to a power state/mode that is greater than a threshold power value.

In some aspects, AP 110 may transmit and STA 120 may use SR 224 to receive a packet (e.g., request packet) that includes an indication that indicates a process to perform in relation to awakening PR 222. In some aspects, the process incudes PR 222 and/or SR 224 entering into an awaken mode, in which at least PR 222 is in a high power state/mode or is powered up/on or SR 224 is in a low power state/mode or is powered down/off. In some aspects, the process includes using PR 222 to negotiate parameters with AP 110 for entering into an awaken mode, in which at least PR 222 is in a low power state/mode or is powered down/off or SR is in a high power state/mode or is powered up/on. In some aspects, after performing such process, STA 120 may enter into the awaken mode.

In some aspects, the primary/main and/or secondary/awaken receiver/radio of an apparatus may receive an awaken request packet that includes an indication/indicia/field/frame/portion that indicates an action/process/operation to perform in relation to awakening the primary/main and/or secondary/awaken radio. For example, such an action/process/operation may include that the apparatus or its primary/main and/or secondary/awaken radio will (1) enter into an awaken mode (e.g., a mode in which the primary/main radio/receiver and/or secondary/awaken radio/receiver is powered down/off (e.g., relatively low power state) or powered up/on (e.g., in a relatively high/normal power state)), (2) receive/transmit or negotiate (e.g., parameters) from/with another apparatus (e.g., AP) for entering into an awaken mode (as described herein), (3) (i) receive/transmit or negotiate (e.g., parameters) from/with another apparatus (e.g., AP) for entering into an awaken mode (as described herein)) and subsequently (ii) enter into an awaken mode (as described herein), or (4) terminate, end, or exit an awaken mode (as described herein).

In some aspects, AP 110 and STA 120 may utilize the UL communication 310 and/or DL communication 312 to communication information that is any one or more of the following: indicating a period of time (e.g., transition period 338) corresponding to transitioning from a first state comprising a doze state or low power state/mode to a second state comprising an awake state or a high power state/mode; channel information associated with SR 224; duty cycle information, which may include a duty cycle preferred by STA 120; beacon information; one or more class of operation; and/or one or more supported operations. In some aspects, in accordance with any one or more of such communicated information, STA 120 may transition from the first state to the second state.

In some aspects, an apparatus (e.g., AP and/or STA) may transmit, receive, and/or negotiate a field, parameter, data, information, information element, or indication indicating a period of time corresponding to/associated with transitioning from a/one state (e.g., awake, doze, power save, or active state) to another state (e.g., awake, doze, power save, or active state) after, in response to, and/or in association with transmitting, receiving, and/or negotiating a particular packet, data packet, transmission, or other information, such as an awaken packet, request packet, or awaken request packet. In some aspects, an apparatus (e.g., AP and/or STA) may perform an operation (e.g., transition from one state/mode to another state/mode) in accordance with such field, parameter, data, information, information element, or indication.

In some aspects, an apparatus (e.g., AP and/or STA) may transmit, receive, and/or negotiate a field, parameter, data, information, information element, or indication indicating one or more settings/parameters/capabilities of that apparatus (e.g., AP and/or STA) in relation to a power mode, mode of operation, an operation, and/or communication parameters/settings while operating in or transition from/to a particular mode (e.g., power save mode, awake mode, doze mode, or active mode). Such settings/parameters/capabilities may include channel state information (e.g., associated with the main/primary and/or secondary radio/receiver), channel information (e.g., associated with the main/primary and/or secondary radio/receiver), a group identifier (e.g., a group of APs and/or STAs), an individual identifier (e.g., of the apparatus (e.g., a transmitting/receiving/destined/intended AP/STA), its primary/main radio/receiver, or it secondary radio/receiver), duty cycle information (e.g., a preferred/requested duty cycle by the apparatus, a mandatory/assigned duty cycle to the apparatus, etc.) (wherein duty cycle information may include an absolute or relative period of time that the main/primary and/or secondary receiver/radio is ON in relation to or as compared to an absolute or relative period of time that the main/primary and/or secondary receiver/radio is OFF), symbol information, beacon information, a class of operations, supported operations, or other suitable aspects. In some aspects, an apparatus (e.g., AP and/or STA) may perform an operation (e.g., transition from one state/mode to another state/mode, operate in a particular state/mode, etc.) in accordance with such field, parameter, data, information, information element, or indication.

In some aspects, an apparatus (e.g., AP/STA) may receive/transmit information that incorporate, integrate, encode, combine, merge, embed, or otherwise include information associated with a basic service set (e.g., to which that apparatus (e.g., AP) or another apparatus (e.g., that receiving STA, another STA, etc.) is associated) in/within/into a number, value, field, parameter, or other data portion (e.g., a data portion that is included in an end portion of a communication/transmission (e.g., instead of having an explicit data portion that includes only such information associated with the basic service set)). In some aspects, such number, value, field, parameter, or other data portion includes information that serves more than one function, wherein one of the more than one function is to provide information associated with the basic service set. Such number, value, field, parameter, or other data portion may be, for example, an error-detecting code/value/number, a cyclic redundancy check value/number/sequence/code, a frame check sequence/value/number/code. In some aspects, an apparatus may, based on such number, value, field, parameter, or other data portion, determine two or more information, wherein at least one of such information includes information associated with the basic service set (e.g., the apparatus may determine whether the data packet, field, information, etc. that included such number, value, field, parameter, or other data portion was destined to that apparatus (e.g., the apparatus that received it) based on such information associated with the basic service set) (e.g., the apparatus may determine whether the data packet, field, information, etc. that included such number, value, field, parameter, or other data portion is associated with the basic service set to which the that apparatus (e.g., the apparatus that received it) is associated) (e.g., the apparatus may obtain or associate its basic service set information from the basic service set information included in the data packet, field, information, etc. that included such number, value, field, parameter, or other data portion was destined to that apparatus (e.g., the apparatus that received it)).

In some aspects, the UL communication 310 may be or include a field indicating a duration of time during which SR 224 will operate according to a high/higher power state/mode or on-mode during/for the one or more subsequent/future communications. Accordingly, in some aspects, STA 120 may transmit (e.g., using PR 222) and AP 110 may receive the field indicating a duration of time during which SR 224 will operate according to a high/higher power state/mode or on-mode during the one or more subsequent/future communications. In some aspects, such subsequent/future communications may include communication of the packet 320, and such high/higher power state/mode or on-mode may occur when SR 224 is in the high power states/modes 324, 328.

In some aspects, e.g., utilizing UL communication 310 and/or DL communication 312, AP 110 and/or STA 120 may communicate a frame that includes a field indicating whether STA 120 is capable of receiving a first subsequent/future communication using a first attribute, including at least one of a communication channel, frequency range, center frequency, or bandwidth. In some aspects, the first subsequent/future communication comprises a beacon. In some aspects, AP 110 may transmit and STA 120 may receive a second subsequent/future communication using a second attribute that is different from the first attribute. For example, a value of at least one of a communication channel, a frequency range, a center frequency, and/or a bandwidth of the first subsequent/future communication may be different from a value of at least one of a communication channel, a frequency range, a center frequency, and/or a bandwidth of the second subsequent/future communication. In some aspects, the second subsequent/future communication may be different from the first subsequent/future communication. In some aspects, the second subsequent/future communication may include or may be the packet 320.

As described in greater detail herein, in some aspects, an apparatus (e.g., AP and/or STA) may receive/transmit a communication/transmission (e.g., a packet, data packet, a frame, a data frame, an awaken packet, an awaken request packet, a request packet, a response packet, an awaken response packet, a beacon, and/or any various other suitable encapsulation of information), and such communication/transmission may include field(s), signal(s), bit(s), or portion(s) that includes any one or more of the various signals, parameters, values, or other indicia described in greater detail herein. In some aspects, a first communication/transmission may include one or more field(s), signal(s), bit(s), or portion(s) and/or signals, parameters, values, or other indicia that indicates a first/beginning/start time of one or more second/subsequent communications/transmissions (e.g., a packet, data packet, a frame, a data frame, an awaken packet, an awaken request packet, a request packet, a response packet, an awaken response packet, a beacon, and/or any various other suitable encapsulation of information) that are communicated according to a duty cycle. In some aspects, a first communication/transmission may include one or more field(s), signal(s), bit(s), or portion(s) and/or signals, parameters, values, or other indicia that indicates a duration of time between two sequential/consecutive second/sub sequent communications/transmissions (e.g., a packet, data packet, a frame, a data frame, an awaken packet, an awaken request packet, a request packet, a response packet, an awaken response packet, a beacon, and/or any various other suitable encapsulation of information) that are communicated according to a duty cycle.

In some aspects, a first communication/transmission (e.g., a packet, data packet, a frame, a data frame, an awaken packet, an awaken request packet, a request packet, a response packet, an awaken response packet, a beacon, and/or any various other suitable encapsulation of information) may include one or more field(s), signal(s), bit(s), or portion(s) and/or signals, parameters, values, or other indicia that indicates a variation of an attribute (e.g., a bandwidth, a center frequency, or a frequency range) of a second/future communication/transmission (e.g., a packet, data packet, frame, data frame, awaken packet, awaken request packet, request packet, response packet, awaken response packet, a beacon, and/or any various other suitable encapsulation of information) relative to the first communication/transmission (e.g., a packet, data packet, a frame, a data frame, an awaken packet, an awaken request packet, a request packet, a response packet, an awaken response packet, a beacon, and/or any various other suitable encapsulation of information). In some aspects, such an indication of such a variation may be in the form of a bit, value, signal, or other indicia that is used to determine a shift, scaling, factor, offset, deviation, determination, calculation, look-up, and/or other suitable variation of such an attribute (e.g., a bandwidth, a center frequency, or a frequency range). For example, an apparatus (e.g., STA or AP) may utilize such an indication to determine an extent/amount of variation, shift, scaling, factor, offset, deviation of such attribute for a second/future communication/transmission (e.g., a packet, data packet, a frame, a data frame, an awaken packet, an awaken request packet, a request packet, a response packet, an awaken response packet, a beacon, and/or any various other suitable encapsulation of information) (e.g., in relation to the same/similar attribute (e.g., a bandwidth, a center frequency, or a frequency range) of the first communication/transmission (e.g., a packet, data packet, a frame, a data frame, an awaken packet, an awaken request packet, a request packet, a response packet, an awaken response packet, a beacon, and/or any various other suitable encapsulation of information)). In some aspects, the determined extent/amount of variation, shift, scaling, factor, offset, deviation of such attribute (e.g., a bandwidth, a center frequency, or a frequency range) for the first communication/transmission (e.g., a packet, data packet, a frame, a data frame, an awaken packet, an awaken request packet, a request packet, a response packet, an awaken response packet, a beacon, and/or any various other suitable encapsulation of information) is relative to, based on, and/or not independent of/from such attribute (e.g., a bandwidth, a center frequency, or a frequency range) of the first communication/transmission (e.g., a packet, data packet, a frame, a data frame, an awaken packet, an awaken request packet, a request packet, a response packet, an awaken response packet, a beacon, and/or any various other suitable encapsulation of information).

In some aspects, a communication/transmission (e.g., a packet, data packet, a frame, a data frame, an awaken packet, an awaken request packet, a request packet, a response packet, an awaken response packet, a beacon, and/or any various other suitable encapsulation of information) may include one or more field(s), signal(s), bit(s), or portion(s) and/or signals, parameters, values, or other indicia that indicates whether an apparatus (e.g., STA or AP) is capable of, is enabled to, is configured to, is willing to, or can/will communicate (e.g., transmit/receive) a first subsequent/future communication/transmission (e.g., a packet, data packet, a frame, a data frame, an awaken packet, an awaken request packet, a request packet, a response packet, an awaken response packet, a beacon, and/or any various other suitable encapsulation of information) using a first attribute (e.g., communication channel, frequency range, center frequency, bandwidth, etc.) and communicate (e.g., transmit/receive) a second subsequent/future communication/transmission (e.g., a packet, data packet, a frame, a data frame, an awaken packet, an awaken request packet, a request packet, a response packet, an awaken response packet, a beacon, and/or any various other suitable encapsulation of information) using a second attribute (e.g., communication channel, frequency range, center frequency, bandwidth, etc.) that is different from the first attribute.

In some aspects, at block 404, AP 110 may await receipt of the packet 320. For example, STA 120 may await receipt from time T₃ to time T₆. In some aspects, though not illustrated in FIG. 3 , AP 110 may transmit and STA 120 may receive (e.g., using SR 224) a beacon that includes information corresponding to timing information for synchronizing communications with AP 110. In some aspects, the beacon may be received using SR 224 when SR 224 is turned/powered on or in a high/higher power state/mode and/or while PR 222 is turned/powered off or in a low/lower power state/mode.

The apparatus may utilize such an indicator (e.g., a counter, counter value, etc., as described in greater detail herein) to determine whether an updated identifier/value for one or more parameters of a basic service set (BSS) (e.g., to which the apparatus (e.g., STA or AP) is or is not yet a member or assigned) is available for the apparatus (e.g., STA or AP).

In some aspects, the packet 320 may be configured to awaken a single apparatus. In some aspects, the packet 320 may be configured to awaken a plurality of apparatuses associated with or assigned a particular identifier. In some aspects, the packet comprises information indicating a time by which to complete an awaken procedure. In some aspects, such awakening comprises STA 120 altering a power state/mode or turning/powering on/up PR 222. In some aspects, the packet 320 includes information indicating or identifying which receiver(s) of that packet 320 is/are intended recipients. In some aspects, the information indicates that the packet 320 (e.g., awaken packet) is intended for a specific receiver, every/all receivers that receive that packet 320 (e.g., awaken packet), or a plurality of specific receivers that does not necessarily include all receivers that receive the packet 320 (e.g., awaken packet).

In some aspects, the packet 320 may include information indicating whether to communicate a response (e.g., response 330) to the packet 320.

In some aspects, the awaken packet may be configured to awaken a single apparatus. In some aspects, the awaken packet may be configured to awaken a plurality of apparatuses (e.g., a plurality of apparatuses associated with or assigned a particular identifier (e.g., group identifier)). In some aspects, ‘awaken’ may include causing the apparatus (that received the awaken packet) to alter the power state or power/turn on/up the primary radio(s)/receiver(s), the secondary radio(s)/receiver(s), and/or any other component of the apparatus. In some aspects, the awaken packet includes information indicating a time to begin a respective awaken procedure by one or more apparatus. In some aspects, the awaken packet may include information indicating a time by which to complete a respective awaken procedure by each of the one or more apparatus.

In some aspects, an awaken request packet may be configured to include various fields or information. In some aspects, such fields/information may include information indicating a time by which one or more receivers of the (respective) awaken request packet(s) shall finish an awaken procedure that transitions that/those receiver(s), or any one or more of its receiver(s)/radio(s), from an off/inactive/doze/low-/lower-power state/mode/configuration to an on/active/high-/higher-power state/mode/configuration. In some aspects, an apparatus (e.g., receiver/recipient) of the awaken request packet may determine when (e.g., a specific time, perhaps in relation to the time of receiving the awaken request packet) (i) to perform an awaken procedure, (ii) to complete an awaken procedure, or (iii) to turn on or power on/up one or more of its receivers/radios.

In some aspects, such fields/information may include information indicating that that awaken request packet is intended for a specific/individual receiver/recipient.

In some aspects, such fields/information may include information indicating that that awaken request packet is intended for all receivers/recipients that receive that awaken request packet. In such aspects, the awaken request packet may not include a specific identifier identifying a specific receiver/recipient of that awaken request packet. In some aspects, such fields/information may include information indicating that that awaken request packet is intended for a plurality of specific receivers/recipients, wherein that plurality of specific receivers/recipients is a subset (i.e., does not include all) of the recipients/receivers that receive that awaken request packet. In some aspects, such fields/information may indicate whether to perform one or more operations by a receiver/recipient of that awaken request packet. For example, such an operation may be to awaken (e.g., transition from an off/inactive/low-/lower-power state/mode/configuration to an on/active/high-/higher-power state/mode/configuration). As another example, such an operation may be to communicate (e.g., transmit) a response (e.g., response packet, awaken response packet, etc.) after, in response to, and/or in association with receiving the awaken request packet.

In some aspects, the packet 320 includes a portion that includes a plurality of identifiers. Each identifier may correspond to a value of an intended recipient apparatus (of the packet 320). In some aspects, the plurality of identifiers may be included in the portion of the packet 320 in a numerically ordered manner. In some aspects, the plurality of identifier may be included in the portion of the packet 320 in a numerically ascending or descending manner. STA 120 may have been assigned an identifier by AP 110 in a preceding communication. In some aspects, in response to processing an identifier (of the plurality of identifiers) that has a value not equal to and not less than a value of the identifier assigned to STA 120, STA 120 may determine to not process any remaining ones of the plurality of identifiers (nor any remaining portion of the packet 320).

In some aspects, STA 120 may process individual ones of the plurality of identifiers of the portion until reaching an identifier that is greater than the identifier assigned to STA 120, at which time STA 120 may determine to not process any remaining ones of the plurality of identifiers (nor any remaining portion of the packet 320). In some aspects, upon reaching an end or final one of the plurality of identifiers without identifying any identifier (of the plurality of identifiers) that is greater than (or that is not equal to and not less than) the identifier assigned to STA 120, STA 120 may determine to not process any remaining ones of the plurality of identifiers (nor any remaining portion of the packet 320). In some aspects, upon reaching an end or final one of the plurality of identifiers and determining that the end or final one of the plurality of identifiers comprises a value that is not equal to and not greater than the identifier assigned to STA 120, STA 120 may determine to not process any remaining ones of the plurality of identifiers (nor any remaining portion of the packet 320).

In some aspects, the on off keying is configured differently based on a rate of data transmission of the packet 320 (or at least some parts thereof). In some aspects, at a first data rate, a first set including one on-duration and one off-duration corresponds to a first value, and/or, at a second data rate, a first set including two on-durations and two off-duration corresponds to the first value. In some aspects, at a first data rate, a second set including one on-duration and one off-duration correspond to a second value, and/or, at a second data rate, a second set including two on-durations and two off-duration correspond to the second value.

In some aspects, as described above, a received packet (e.g., an awaken packet, an awaken request packet, etc.) may be modulated in various ways without deviating from the scope of the present disclosure.

In some aspects, the on off keying may be configured in various ways without deviating from the scope of the present disclosure. In some aspects, the on off keying may be configured differently based on the rate of data transmission of the packet (e.g., an awaken packet, an awaken request packet, etc.).

In some aspects, when communication of the packet (e.g., an awaken packet, an awaken request packet, etc.) is according to a first data rate, an off/off-duration signal(s)/symbol(s) of/for a first duration (e.g., X microseconds) followed by an on/on-duration signal(s)/symbol(s) for a second duration, which may be the same (e.g., X microseconds) as the first duration (e.g., X microseconds) or different from (e.g., Y microseconds) the first duration (e.g., X microseconds), may carry or correspond to a first value, and an on/on-duration signal(s)/symbol(s) of/for a first duration (e.g., X microseconds) followed by an off/off-duration signal(s)/symbol(s) for a second duration, which may be the same (e.g., X microseconds) as the first duration (e.g., X microseconds) or different (e.g., Y microseconds) from the first duration (e.g., X microseconds), may carry or correspond to a second value, which may be different from the first value. In some aspects, such on/on-duration signal(s)/symbol(s) may include a null portion and a payload/signal portion. In some aspects, such a null portion may be for a duration that is shorter than the payload/signal portions. For example, the null portion may have a duration that is one third (e.g., X/3 microseconds) of the on/on-duration signal(s)/symbol(s) (X microseconds), and the payload/signal portion may have a duration that is two thirds (e.g., 2X/3 microseconds) of the on/on-duration signal(s)/symbol(s) (e.g., X microseconds).

In some aspects, when communication of the packet (e.g., an awaken packet, an awaken request packet, etc.) is according to a second data rate, two (or more) on/on-duration signal(s)/symbol(s) each or collectively having a first duration (e.g., A microseconds) followed by two (or more) off/off-duration signal(s)/symbol(s) each or collectively having of/for a second duration (e.g., B microseconds), which may be the same (e.g., A microseconds) as the first duration (e.g., A microseconds) or different (e.g., B microseconds) from the first duration (e.g., A microseconds), may carry or correspond to a first value, and two (or more) off/off-duration signal(s)/symbol(s) each or collectively having a first duration (e.g., A microseconds) followed by two (or more) off/off-duration signal(s)/symbol(s) each or collectively having of/for a second duration (e.g., B microseconds), which may be the same (e.g., A microseconds) as the first duration (e.g., A microseconds) or different (e.g., B microseconds) from the first duration (e.g., A microseconds), may carry or correspond to a second value. In some aspects, such on/on-duration signal(s)/symbol(s) may include a null portion and a payload/signal portion. In some aspects, such a null portion may be for a duration that is shorter than the payload/signal portions. For example, the null portion may have a duration that is one fourth (e.g., A/4 microseconds) of the on/on-duration signal(s)/symbol(s) (A microseconds), and the payload/signal portion may have a duration that is three quarters (e.g., 3A/4 microseconds) of the on/on-duration signal(s)/symbol(s) (e.g., A microseconds).

In some aspects, the first data rate may be less than the second data rate, or the second data rate may be greater than the first data rate. In some aspects, the second data rate may be lower than the first data rate, or the first data rate may be greater than the second date rate. Although various data rates (e.g., first and second data rates) are described herein, in some aspects, a single data rate (e.g., only a first data rate or only a second data rate) may be sufficient and additional data rates are not necessarily a requirement of the present disclosure, while, in some other aspects, more than a single data rate (e.g., a first data rate and a second data rate) may be required and a single data rate may not necessarily be sufficient. Therefore, various implementations may utilize a single data rate or more than a single data rate without deviating from the scope of the present disclosure.

In some aspects, a communication/transmission (e.g., packet 320) transmitted by AP 110 and received by STA 120 may not include a field that explicitly indicates a data rate of the transmission/communication (e.g., packet 320). In some aspects, the SS includes information useful for an inference (e.g., by STA 120) of a rate of transmission of information in the communication/transmission (e.g. packet 320). In some aspects, STA 120 may infer a first magnitude of the one or more factors when the SS includes the first set/structure of data, and infer a second magnitude of the one or more factors when the SS includes the second set/structure of data. In such aspects, the first set/structure of data is different from the second set/structure of data. In such aspects, the first magnitude of the one or more factors is higher than the second magnitude of the one or more factors, or the second magnitude of the one or more factors is less than the first magnitude of the one or more factors. In such aspects, the first set/structure of data of the SS has a relationship to the second set/structure of data of the SS, or the second set/structure of data of the SS has a relationship to the first set/structure of data of the SS. The second set/structure of data of the SS may be or include a complement of the first set/structure of data of the SS.

In some aspects, a quantity of bits of the first set/structure of data of the SS is a fraction of a quantity of bits of the second set/structure of data of the SS. In some aspects, the number of bits/symbols and/or the duration of the first set/structure of data of the SS is greater than the number of bits/symbols and/or the duration of the second set/structure of data of the SS, or the number of bits/symbols and/or the duration of the second set/structure of data of the SS is less than the number of bits/symbols and/or the duration of the first set/structure of data of the SS. In some other aspects, the number of bits/symbols and/or the duration of the second set/structure of data of the SS is greater than the number of bits/symbols and/or the duration of the first set/structure of data of the SS, or the number of bits/symbols and/or the duration of the first set/structure of data of the SS is less than the number of bits/symbols and/or the duration of the second set/structure of data of the SS.

As mentioned herein, in some aspects, the second data rate may be lower than the first data rate, or the first data rate may be greater than the second date rate. In some aspects, e.g., when communication of the packet 320 is according to a particular data rate (e.g., a low data rate, or a single, predetermined data rate), an on (or on-duration) signal may be characterized by having an energy level above a threshold (e.g., threshold energy level), and an off (or off-duration) signal may be characterized by having an energy level below the threshold (e.g., threshold energy level). In such aspects, if, during the period of time, STA 120 receives a group that includes at least three signals where an initial signal is the same as the penultimate signal and the final signal of the group comprises an off signal, STA 120 may determine that the group of signals received during the period of time corresponds to a first value. In such aspects, if, during the period of time, STA 120 receives a group that includes at least three signals where an initial signal is the same as the penultimate signal and the final signal includes an on signal, STA 120 may determine that the group of signals received during the period of time corresponds to a second value, which may be different from the first value.

In some aspects, as described above, a received packet (e.g., an awaken packet, an awaken request packet, etc.) may be modulated in various ways without deviating from the scope of the present disclosure. In some aspects, as described above, the packet (e.g., an awaken packet, an awaken request packet, etc.) may be modulated using various keying/modulation techniques, such as frequency shift keying, amplitude shift keying, phase shift keying, on off keying, quadrature amplitude modulation, and/or various other types of modulation or keying/modulation techniques. In some aspects, the on off keying may be configured in various ways without deviating from the scope of the present disclosure. In some aspects, the on off keying may be configured differently based on the rate of data transmission of the packet (e.g., an awaken packet, an awaken request packet, etc.).

In some aspects, when communication of the packet (e.g., an awaken packet, an awaken request packet, etc.) is according to a second data rate, which may be the same as or different from (e.g., lesser/lower than or greater/higher than) the aforementioned first data rate (described above), an apparatus (e.g., STA/AP) may determine information, a value, or an information/informational value associated with symbols/signals received during a certain period of time. In some aspects, such an apparatus (e.g., STA/AP), when communicating according to such second data rate, may determine that the symbols/signals received during such a period of time contains or corresponds to a first value/information/informational-value when/if, during such a period of time: (1) such apparatus receives/received a group of at least three signals/symbols comprising no more than two or two or more on/on-duration signal(s)/symbol(s) (e.g., wherein an on/on-duration signal/symbol may be characterized by having a detectable energy level above a certain threshold) separated by no more than one or more than one off/off-duration signal(s)/symbol(s) (e.g., wherein an off/off-duration signal/symbol may be characterized by having a detectable energy level below a certain threshold), and wherein a final/last symbol/signal of such grouping is/includes/comprises an off/off-duration signal/symbol; (2) such apparatus receives/received a group of at least three signals/symbols comprising no more than two or two or more off/off-duration signal(s)/symbol(s) separated by no more than one or more than one on/on-duration signal(s)/symbol(s) and wherein a first/initial symbol/signal of such grouping is/includes/comprises an on/on-duration signal/symbol; and/or (3) such apparatus receives/received a group of at least three signals/symbols wherein an initial symbol/signal is similar or the same as the penultimate signal/symbol (e.g., both on/on-durations signals/symbols or both off/off-duration symbols/signals) and (i) the last/final symbol is an off/off-duration symbol/signal and/or (ii) the first/initial symbol/signal is an on/on-duration signal/symbol. In some aspects, the duration of time associated with each signal/symbol described above is the same (e.g., each comprises A microseconds). In some aspects, a duration of time associated with each signal/symbol described above is different from one another (e.g., one signal/symbol may have a duration of A microseconds while one (or more) signal(s)/symbol(s) may have a duration of B microseconds).

In some aspects, such an apparatus (e.g., STA/AP), when communicating according to such second data rate, may determine that the symbols/signals received during such a period of time contains or corresponds to a second value/information/informational-value, which may be the same as or different from the aforementioned first value/information/informational-value (described above), when/if, during such a period of time: (1) such apparatus receives/received a group of at least three signals/symbols comprising no more than two or two or more on/on-duration signal(s)/symbol(s) (e.g., wherein an on/on-duration signal/symbol may be characterized by having a detectable energy level above a certain threshold) separated by no more than one or more than one off/off-duration signal(s)/symbol(s) (e.g., wherein an off/off-duration signal/symbol may be characterized by having a detectable energy level below a certain threshold), and wherein a final/last symbol/signal of such grouping is/includes/comprises an on/on-duration signal/symbol; (2) such apparatus receives/received a group of at least three signals/symbols comprising no more than two or two or more off/off-duration signal(s)/symbol(s) separated by no more than one or more than one on/on-duration signal(s)/symbol(s) and wherein a first/initial symbol/signal of such grouping is/includes/comprises an off/off-duration signal/symbol; and/or (3) such apparatus receives/received a group of at least three signals/symbols wherein an initial symbol/signal is similar or the same as the penultimate signal/symbol (e.g., both on/on-durations signals/symbols or both off/off-duration symbols/signals) and (i) the last/final symbol is an on/on-duration symbol/signal and/or (ii) the first/initial symbol/signal is an off/off-duration signal/symbol. In some aspects, a duration of time associated with each signal/symbol described above is different from one another (e.g., one signal/symbol may have a duration of A microseconds while one (or more) signal(s)/symbol(s) may have a duration of B microseconds). In some aspects, a duration of time associated with each signal/symbol described above is similar to or the same as one another (e.g., one signal/symbol may have a duration of A microseconds while one (or more) signal(s)/symbol(s) may have a duration of exactly or approximately A microseconds).

In some aspects, the packet 320 may include a preamble. In some aspects, the preamble is communicated using a first bandwidth or a first frequency range, and the SS is communicated using a second bandwidth or second frequency range. In some aspects, the first bandwidth or first frequency range comprises a value or range of values that is greater than or a multiple of the second bandwidth or second frequency range. In some aspects, such multiple comprises a value of X, which may be an integer greater than one. In some aspects, the first bandwidth or frequency range comprises a same center frequency as the second bandwidth or second frequency range.

As described in greater detail herein, in some aspects, an apparatus (e.g., AP and/or STA) may receive/transmit a communication/transmission e.g., a packet, data packet, a frame, a data frame, an awaken packet, an awaken request packet, a request packet, a response packet, an awaken response packet, a beacon, and/or any various other suitable encapsulation of information), and such communication/transmission may include field(s), signal(s), bit(s), or portion(s) that includes any one or more of the various signals, parameters, values, or other indicia described in greater detail herein. In some aspects, such field(s), signal(s), bit(s), or portion(s) may include or be a preamble, a header, a timing management signal, a synchronization value/counter/signal, and/or various other suitable types of information/data, as described in greater detail herein. In some aspects, the preamble and/or header of such field(s), signal(s), bit(s), or portion(s) may be communicated using/in, be included in, or span a first bandwidth or first frequency range, and the timing management signal, synchronization value/counter/signal, and/or one or more other portions of such field(s), signal(s), bit(s), or portion(s) may be communicated using/in, be included in, or span a second bandwidth or second frequency range. In some aspects, the first bandwidth or first frequency range comprises a value or a range of values that is greater than, or a multiple of (e.g., 2X/2-times, 3X/3-times, 4X/4-times, 5X/5-times, 6X/6-times etc.), the second bandwidth or second frequency range. In some aspects, the first bandwidth or first frequency range comprises a same center frequency as the second bandwidth or second frequency range.

In some aspects, the second bandwidth or second frequency range comprises a value or a range of values that is less than, a subset of, or a fraction of (e.g., one-half, one-third, one-fourth, one-fifth, one-sixth, etc.) the second bandwidth or second frequency range. In some aspects, no more than a single timing management signal and/or synchronization signal (of such field(s), signal(s), bit(s), or portion(s)) spanning, communicated in/using, or included in the second frequency range or second bandwidth is communicated with the header and/or preamble (of such field(s), signal(s), bit(s), or portion(s)) spanning, communicated in/using, or included in the first frequency range or first bandwidth. In some aspects, at least a portion or some of the first bandwidth or first frequency range is included in the second bandwidth or second frequency range, and at least a portion or some of the first bandwidth or first frequency range is not included in the second bandwidth or second frequency range. In some aspects, all of the second bandwidth or second frequency range is included in or is the same as the first bandwidth or first frequency range, and not all of the first bandwidth or first frequency range is included in or the same as the second bandwidth or second frequency range.

In some aspects, in response to receiving the packet 320, STA 120 may initiate a transition of PR 120 from a low power state/mode, turned off state or powered down state to a high power, turned on state, or powered up state. In some aspects, STA 120 may transmit and AP 110 may receive a response 330 to the packet 320. STA 120 may transmit the response 330 utilizing PR 222, as illustrated in FIG. 3 , or SR 224, even though not illustrated in FIG. 3 . In some aspects, after transmitting the response 330 to the packet 320, AP 110 may transmit and STA 120 may receive a message 332, which may be communicated in association with the aforementioned response 330. STA 120 may receive the message 332 utilizing PR 222, as illustrated in FIG. 3 , or SR 224, even though not illustrated in FIG. 3 . In some aspects, in response to receiving the message 332, AP 110 may initiate a transition from operating according to a mode/state wherein SR 224 is in a high power state/mode, turned on, or powered up to operating according to a mode/state wherein SR 224 is in a low power state/mode, turned off, or powered down. In some aspects, if/after STA 120 transmits the response 330 (e.g., using PR 222 and/or SR 224) to the packet 320 to AP 110 and if/after STA 120 receives a packet (e.g., message 332) associated with the transmitted response 330, STA 120 may initiate a transition of SR 224 from a high power state/mode, a turned on state, or a powered up state to a low power state/mode, a turned off state, or a powered down state.

In some aspects, an apparatus (e.g., AP and/or STA) having a primary/main radio/receiver and/or secondary receiver may be configured to, maintain in a same/similar power/operation mode/state, turn-on/power-up, and/or turn-off/power-down one or more such radio/receivers based on various conditions, parameters, factors, thresholds, and other suitable aspects. In some aspects, such an apparatus may be configured to operate in or according to the first mode/state/configuration described above (in which its primary/main radio/receiver may be/operate in an on/high-/higher-/active power mode/state/configuration and its secondary radio/receiver may be/operate in an off/low-/lower-/inactive/doze power mode/state/configuration).

In some aspects, such an apparatus may be configured to operate in or according to a sixth mode/state/configuration in which its primary/main receiver/radio is switching, or at least transitioning, from being/operating in an off/low-/lower-/inactive/doze power mode/state/configuration to being/operating in an on/high-/higher-/active power mode/state/configuration while its secondary radio/receiver is/operates in an on/high-/higher-/active power mode/state/configuration.

In some aspects, such an apparatus may be configured to communicate/receive a packet/frame (e.g., an awaken packet, a request packet, or awaken request packet, as described in greater detail herein) while such an apparatus is operating in or according to the third mode/state/configuration described above (in which its primary/main radio/receiver may be/operate in an off/low-/lower-/inactive/doze power mode/state/configuration and its secondary radio/receiver may be/operate in an (e.g., always/continuously) on/high-/higher-/active power mode/state/configuration). In some aspects, after, in response to, and/or in association with receiving such a packet (e.g., an awaken packet, a request packet, or awaken request packet, as described in greater detail herein), such an apparatus may be configured to switch, or at least initiate a transition, from (1) operating in or according to the third mode/state/configuration described above (in which its primary/main radio/receiver may be/operate in an off/low-/lower-/inactive/doze power mode/state/configuration and its secondary radio/receiver may be/operate in an (e.g., always/continuously) on/high-/higher-/active power mode/state/configuration) to (2) operating in or according to the fifth mode/state/configuration described above (in which its primary/main receiver/radio is/operates in an on/high-/higher-/active power mode/state/configuration while its secondary radio/receiver is/operates in an on/high-/higher-/active power mode/state/configuration) and/or the sixth mode/state/configuration described above (in which its primary/main receiver/radio is switching, or at least transitioning, from being/operating in an off/low-/lower-/inactive/doze power mode/state/configuration to being/operating in an on/high-/higher-/active power mode/state/configuration while its secondary radio/receiver is/operates in an on/high-/higher-/active power mode/state/configuration). In some aspects, such an apparatus may be configured to, after, in response to, and/or in association with receiving such a packet (e.g., an awaken packet, a request packet, or awaken request packet, as described in greater detail herein), maintain its secondary receiver/radio in a same/similar power/operation mode/state/configuration (e.g., in the on/high-/higher-/active power mode/state/configuration).

In some aspects, such apparatus may be configured to, after, in response to, and/or in association with communicating/receiving a response acknowledgement message (e.g., an acknowledgement message transmitted from another apparatus indicating whether the aforementioned response to the aforementioned frame/packet (e.g., such response to such packet/frame being a response packet or awaken response packet, as described in greater detail herein)), switch, or at least initiate a transition, from (1) operating in or according to the fifth mode/state/configuration described above (in which its primary/main receiver/radio is/operates in an on/high-/higher-/active power mode/state/configuration while its secondary radio/receiver is/operates in an on/high-/higher-/active power mode/state/configuration) and/or the sixth mode/state/configuration described above (in which its primary/main receiver/radio is switching, or at least transitioning, from being/operating in an off/low-/lower-/inactive/doze power mode/state/configuration to being/operating in an on/high-/higher-/active power mode/state/configuration while its secondary radio/receiver is/operates in an on/high-/higher-/active power mode/state/configuration) to (2) operating in or according to the first mode/state/configuration described above (in which its primary/main radio/receiver may be/operate in an on/high-/higher-/active power mode/state/configuration and its secondary radio/receiver may be/operate in an off/low-/lower-/inactive/doze power mode/state/configuration). In some aspects, such apparatus may be configured to, after, in response to, and/or in association with communicating/receiving a response acknowledgement message (e.g., an acknowledgement message transmitted from another apparatus indicating whether the aforementioned response to the aforementioned frame/packet (e.g., such response to such packet/frame being a response packet or awaken response packet, as described in greater detail herein)), maintain its primary/main receiver/radio in a same/similar power/operation mode/state/configuration (e.g., is/in an on/high-/higher-/active power mode/state/configuration). In some aspects, such apparatus may be configured to, after in response to, and/or in association with communicating/receiving a response acknowledgement message (e.g., an acknowledgement message transmitted from another apparatus indicating whether the aforementioned response to the aforementioned frame/packet (e.g., such response to such packet/frame being a response packet or awaken response packet, as described in greater detail herein)), switch, or at least initiate a transition, from being or operating according to an on/high-/higher-/active power mode/state/configuration to being/operating in an off/low-/lower-/inactive/doze power mode/state/configuration.

In some aspects, such an apparatus may be configured to (e.g., after receiving the aforementioned packet/frame (e.g., an awaken packet, a request packet, or awaken request packet, as described in greater detail herein) (e.g., by its secondary radio/receiver and/or while its secondary radio/receiver is in an on/high-/higher-/active power mode/state/configuration) switch, or at least initiate a transition, its secondary radio/receiver from an on/high-/higher-/active power mode/state/configuration to an off/low-/lower-/inactive/doze power mode/state/configuration if/only-if/when/only-when/after/only-after-if/only-after (1) at least one frame/packet (e.g., the aforementioned response to the aforementioned frame/packet (e.g., such response to such packet/frame being a response packet or awaken response packet, as described in greater detail herein) is communicated/transmitted to another apparatus and (2) at least one frame/packet associated with that communicated/transmitted packet/frame (e.g., such at least one frame/packet associated with that communicated/transmitted packet/frame being a response acknowledgement message (e.g., an acknowledgement message transmitted from another apparatus indicating whether the aforementioned response to the aforementioned frame/packet)) is communicated/received.

In some aspects, after AP 110 transmits the packet 320, AP 110 may determine whether the transmission was successful based on whether AP 110 receives a response 330 to the transmitted packet 320 during a predetermined period of time after the transmission (e.g., during a time period between time T₆ and time T₉). In some aspects, AP 110 may determine that the transmission was unsuccessful if no response to the packet 320 is received (e.g., by time T₉), and/or may determine that the transmission was successful if a response to the packet 320 was received (e.g., by time T₉).

In some aspects, an apparatus/transmitter (e.g., AP) that transmits an awaken request packet may determine whether such transmission was successful based on whether it receives any (e.g., at least one) packets (e.g., awaken response packets) after, in response to, and/or in association with the transmitted awaken request packet during a period/duration (e.g., preset, predetermined, variable) of time after transmitting the awaken request packet. In some aspects, if the apparatus/transmitter (e.g., AP) receives any (e.g., at least one) packets (e.g., awaken response packet(s)) after, in response to, and/or in association with transmission of the awaken request packet, then the apparatus/transmitter (e.g., AP) may determine that the transmission of the awaken request packet was successful. In some aspects, if the apparatus/transmitter (e.g., AP) receives no packets (e.g., awaken response packets) After, in response to, and/or in association with transmission of the awaken request packet, then the apparatus/transmitter (e.g., AP) may determine that the transmission of the awaken request packet was unsuccessful.

In some aspects, an apparatus/receiver (e.g., STA(s)) may alter, adjust, or otherwise change its state, mode, or other configuration based on its success in receiving a packet (e.g., awaken request packet), and/or based on its success in transmitting a packet (e.g., awaken response packet) after, in response to, and/or in association with receiving another packet (e.g., awaken request packet), during a duration/period (e.g., preset, predetermined, variable, etc.) of time after receiving the that packet (e.g., awaken request packet), and/or within a period of time after initiating/completing an awaken procedure (as described herein). A state, mode, or other configuration may refer to or include the radio/antenna utilized by the apparatus/receiver (e.g., STA(s)), the power state or relative power utilization by the apparatus/receiver (e.g., STA(s)) or any of its antenna(s)/receiver(s), and/or any other suitable aspects of the apparatus/receiver (e.g., STA(s)), or as otherwise described herein.

In some aspects, a mode/state/configuration may be a relatively high-/higher-power mode/state/configuration of operation, and another mode/state/configuration may be a relatively lower-power mode/state/configuration of operation. In some aspects, the apparatus/receiver (e.g., STA(s)) may alter, adjust, or otherwise change its state, mode, or other configuration, if/when the apparatus/receiver (e.g., STA(s)) is unsuccessful in receiving any/all packets (e.g., awaken request packets), and/or is unsuccessful in transmitting any/all packets (e.g., awaken response packets) after, in response to, and/or in association with receiving another packet (e.g., awaken request packet), e.g., during a period/duration (e.g., preset, predetermined, variable, etc.) of time after receiving such packet (e.g., awaken request packet), and/or within a period of time after initiating/completing an awaken procedure (as described herein).

In some aspects, as described in greater detail herein, AP 110 may transmit and STA 120 may (e.g., using SR 224) receive the packet 320 while PR 222 is in a low power state/mode, a turned off state, or in a low power state/mode. In some aspects, the received packet 320 includes a field that indicates a version value. In some aspects, STA 120 may do one or more of the following: (A) use the version value to determine whether settings or parameters associated with a basic service set (BSS) are up-to-date or current; (B) use the version value to determine whether to update settings or parameters associated with the BSS; and/or (C) compare the version value (included in the received packet 320) with a previously received version value and, based on the comparison, to determine whether to perform an operation to update the settings or parameters associated with the BSS.

In some aspects, the settings or parameters associated with the BSS may affect communications using at least one of PR 222 or SR 224. In some aspects, in response to receiving the version value, and/or based on any one or more of the aforementioned (A), (B), and/or (C), STA 120 may determine to perform an operation to update such parameters or settings associated with the BSS. In some aspects, the operation to update the settings or parameters of the BSS includes STA 120 awakening PR 222. In some aspect, the operation to update the settings or parameters of the BSS includes STA 120 communicating a request to AP 110 and subsequently receiving a response from AP 110.

In some aspects, an apparatus (e.g. AP) may transmit and another apparatus (e.g., STA) may receive a packet, frame, beacon, or other information comprising various field. In some aspects, non-limiting examples of such packet, frame, beacon, or other information may include an awaken packet, an awaken request packet, an awaken beacon, or various other suitable forms of data/information. In some aspects, such received packet, frame, beacon, or other information may be received by the primary/main radio/receiver of the other apparatus (e.g., STA) (e.g., while the secondary/awaken radio/receiver of the other apparatus (e.g., STA) is turned off or in a low power state). In some aspects, such received packet, frame, beacon, or other information may be received by the secondary/awaken radio/receiver of the other apparatus (e.g., STA) (e.g., while the main/primary radio/receiver of the other apparatus (STA) is turned off or in low power state). In some aspects, such received packet, frame, beacon, or other information may include a field, value, counter, indicator, or number of bits that indicates a version/modification/alteration/synchronization/counter/change number/indicia/value. In some aspects, the other apparatus (e.g., STA) may utilize such version/modification/alteration/synchronization/counter/change number/indicia/value to determine whether information/settings/parameters associated with the basic service set (e.g., with which the apparatus(es) (e.g., AP and/or STA) is/are associated) (e.g., as stored in/by the other apparatus (e.g., STA)) are updated/up-to-date/current and/or whether to update such information/settings/parameters associated with the basic service set (e.g., with which the apparatus(es) (e.g., AP and/or STA) is/are associated) (e.g., as stored in/by the other apparatus (e.g., STA)). In some aspects, the other apparatus (e.g., STA) may compare such received version/modification/alteration/synchronization/counter/change number/indicia/value with a stored or another previously received version/modification/alteration/synchronization/counter/change number/indicia/value and, based on such comparison, determine whether to perform an operation to update such information/settings/parameters associated with the basic service set (e.g., with which the apparatus(es) (e.g., AP and/or STA) is/are associated) (e.g., as stored in/by the other apparatus (e.g., STA)). In some aspects, such information/settings/parameters associated with the basic service set may impact/affect communications by/using the primary/main receiver/radio of the apparatus (e.g., STA)). In some aspects, such information/settings/parameters associated with the basic service set may impact/affect communications by/using the secondary/awaken receiver/radio of the apparatus (e.g., STA).

After, in response to, and/or in association with receiving the aforementioned information (version/modification/alteration/synchronization/counter/changenumber/indicia/value), or in association with or based upon the aforementioned comparison (comparison of such received version/modification/alteration/synchronization/counter/changenumber/indicia/value with a stored or another previously received version/modification/alteration/synchronization/counter/change number/indicia/value) (e.g., as stored in/by the other apparatus (e.g., STA)) or any of the aforementioned determinations (e.g., (i) determining whether information/settings/parameters associated with the basic service set (e.g., with which the apparatus(es) (e.g., AP and/or STA) is/are associated) (e.g., as stored in/by the other apparatus (e.g., STA)) are updated/up-to-date/current), (ii) determining whether to update such information/settings/parameters associated with the basic service set (e.g., with which the apparatus(es) (e.g., AP and/or STA) is/are associated) (e.g., as stored in/by the other apparatus (e.g., STA)), (iii) or determine whether to perform an operation to update such information/settings/parameters associated with the basic service set (e.g., with which the apparatus(es) (e.g., AP and/or STA) is/are associated), the apparatus (e.g., STA) may make a determination.

In some aspects, such a determination is that no further action is required in relation to the information/settings/parameters associated with the basic service set (e.g., when the information/settings/parameters associated with the basic service set is up-to-date). In some actions, such a determination is to perform an operation to update such information/settings/parameters associated with the basic service set (e.g., when the information/settings/parameters associated with the basic service set is not up-to-date). In some aspects, such an operation to update such information/settings/parameters associated with the basic service set may be for the apparatus (e.g., STA) to awaken or enter into a high(er) power state (e.g., with respect to its primary/main radio). In some aspects, such an operation to update such information/settings/parameters associated with the basic service set may be for the apparatus (e.g., STA) to update/change its stored version/modification/alteration/synchronization/counter/change number/indicia/value based on the received version/modification/alteration/synchronization/counter/change number/indicia/value. In some aspects, such an operation to update such information/settings/parameters associated with the basic service set may be for the apparatus (e.g., STA) to communicate a request (e.g., probe request) to another apparatus (e.g., AP) and/or subsequently receive a response (e.g., probe response) after, in response to, and/or in association with its request (e.g., probe request). In some aspects, the response to its request may include updated information/settings/parameters associated with the basic service. In some aspects, such an operation to update such information/settings/parameters associated with the basic service set may be for the apparatus (e.g., STA) to awaken the primary/main receiver/radio to decode/process/obtain information contained in at least a portion of the aforementioned received packet, frame, beacon, or other information.

In some aspects, the packet 320 includes a counter or counter value. In some aspects, the counter or counter value is regarding an availability of an updated value for one or more parameters of a BSS (e.g., with/to which the apparatus is associated). In some aspects, the counter or counter value is regarding whether an updated value for one or more parameters of a BSS (with/to which the apparatus is associated) is available for STA 120. In some aspects, STA 120 is configured to utilize the counter or counter value to determine whether an updated value for one or more parameters of a BSS (with/to which the apparatus is associated) is available.

In accordance with many aspects described herein, STA 120 may be configured to operate according to any one or more of the following configurations: (1) a first configuration in which PR 222 operates in a high/active power state/mode (e.g., a continuous high/active power state/mode) while its SR 224 operates in a low/doze power state/mode; (2) a second configuration in which PR 222 alternates between a period of operating in a high/active power state/mode and a period of operating in a low/doze power state/mode according to a duty cycle or periodicity while its SR 224 operates in a low/doze power state/mode; (3) a third configuration in which PR 222 operates in a low/doze power state/mode and SR 224 operates in a high/active power (e.g., a continuous high/active power state/mode); and/or (4) a fourth configuration in which PR 222 operates in a low/doze power mode and SR 224 alternates between a period of operating in a high/active power mode followed by a period of operating in a low/doze power mode according to a duty cycle or periodicity.

In some aspects, STA 120 may use PR 222 and/or SR 224 to receive a signal from AP 110 and transition between any two (or more) of the four aforementioned configurations (listed above as (1) through (4)) after or based on a signal received from AP 110. In some aspects, as described in greater detail herein, STA 120 may use SR 224 to receive the packet 320 and, in response to receiving the packet 320, alter a mode of PR 222 from a low/doze power mode to a high/active power mode. In some aspects, STA 120 may transition from the first configuration (see (1) above) or the second configuration (see (2) above) to the third configuration (see (3) above) or the fourth configuration (see (4) above), if/when the apparatus determines that a buffer of a transmitting device (e.g., AP 110) with which STA 120 intends to communicate does not have a frame or packet addressed to it.

In some aspects, after, in response to, and/or in association with receiving the awaken request packet, the apparatus may turn-on/activate/enable/power-increase or otherwise alter a mode/state/configuration of the secondary receiver/radio from a low-/lower-/inactive/off/doze power state/mode/configuration to a high-/higher-/active/on power state/mode/configuration.

In some aspects, a (receiving) apparatus (e.g., STA/AP) may transition/change to the third mode/state/configuration (as described herein) or the fourth mode/state/configuration described above (in which its primary/main radio/receiver may be/operate in an off/low-/lower-/inactive/doze power mode/state/configuration and its secondary radio/receiver may cycle/alternate between a period of being/operating in an on/high-/higher-/active power mode/state/configuration followed by a period of being/operating in an off/low-/lower-/inactive/doze power mode/state/configuration (or vice versa), e.g., according to a duty cycle, schedule, frequency, or periodicity), e.g., from the first mode/state/configuration described above (in which its primary/main radio/receiver may be/operate in an on/high-/higher-/active power mode/state/configuration and its secondary radio/receiver may be/operate in an off/low-/lower-/inactive/doze power mode/state/configuration) or from the second mode/state/configuration described above (in which its primary/main radio/receiver may cycle/alternate/vary between a period/duration of being/operating in an on/high-/higher-/active power mode/state/configuration and/followed by a period/duration of being/operating in an off/low-/lower-/inactive/doze power mode/state/configuration (or vice versa), e.g., according to a duty cycle, schedule, frequency, or periodicity and its secondary radio/receiver may be/operate in an off/low-/lower-/inactive/doze power mode/state/configuration), when/if or only if/when (i) that (receiving) apparatus determines that a buffer of another (transmitting) apparatus (e.g., AP/STA) with which it is/intends/destined to communicate is empty or does not have a packet/frame addressed to that (receiving) apparatus and/or (ii) the (receiving) apparatus determines that a (transmission) buffer of that (receiving) apparatus is empty or does not have a packet/frame addressed to that other (transmitting) apparatus.

In some aspects, such communication/transmission may be in accordance with such an indication when that communication/transmission occurs (1) after/upon expiration/termination of such period of time corresponding to/associated with transitioning from one state (e.g., awake, doze, power save, or active state) to another state (e.g., awake, doze, power save, or active state) and/or (2) the receiving apparatus (e.g., STA) and/or any of its radios/transceivers are currently/already operating in the other state (e.g., awake, doze, power save, or active state).

As another example, a STA may receive or schedule (e.g., receipt of) a communication/transmission (e.g., a packet, data packet, a frame, a data frame, an awaken packet, an awaken request packet, a request packet, a response packet, an awaken response packet, a beacon, and/or any various other suitable encapsulation of information) in accordance with (1) such indication indicating a period of time corresponding to/associated with transitioning from one state (e.g., awake, doze, power save, or active state) to another state (e.g., awake, doze, power save, or active state), and/or (2) such information indicating a time by which one or more receivers of the (respective) awaken request packet(s) shall finish an awaken procedure that transitions that/those receiver(s), or any one or more of its receiver(s)/radio(s), from a low-power state to a high power state. In some aspects, such communication/transmission may be in accordance with such an indication when that communication/transmission occurs (1) after/upon expiration/termination of such period of time corresponding to/associated with transitioning from one state (e.g., awake, doze, power save, or active state) to another state (e.g., awake, doze, power save, or active state), and/or (2) the receiving apparatus (e.g., STA) and/or any of its radios/transceivers are currently/already operating in the other state (e.g., awake, doze, power save, or active state).

In some aspects, at block 408, AP 110 and STA 120 may perform UL and/or DL communication(s). For example, STA 120 may utilize PR 222 for UL/DL communication 340 at time T₁₁. In some aspects, at block 410, AP 110 and/or STA 120 (e.g., using PR 222) may transmit one or more communications that result in termination or teardown of one or more of the negotiated parameters, settings, and/or configurations relating to operation(s) of AP 110, STA 120, PR 222, and/or SR 224, as described in greater detail herein.
